Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What are the coordinates of a point?

Back

A pair of numbers (x, y) that define the position of a point on the coordinate plane.

Front

What does the x-coordinate represent?

Back

The horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent?

Back

The vertical position of a point on the coordinate plane.

Front

How do you plot the point (4, 9)?

Back

Start at the origin (0, 0), move 4 units to the right (x-axis), and then move 9 units up (y-axis).

Front

What is the origin in the coordinate plane?

Back

The point where the x-axis and y-axis intersect, represented as (0, 0).

Front

What quadrant is point (3, 4) located in?

Back

Quadrant I, where both x and y coordinates are positive.

Front

What quadrant is point (-3, -2) located in?

Back

Quadrant III, where both x and y coordinates are negative.

Front

What is the distance from the origin to the point (3, 4)?

Back

The distance is 5 units, calculated using the Pythagorean theorem: √(3² + 4²) = 5.

Front

What is the significance of the signs of coordinates?

Back

Positive x indicates right, negative x indicates left; positive y indicates up, negative y indicates down.
